Description

Technical Field

[0001] The invention relates to an atomizer structure of a vapor mist generating device, and in particular to an oil locking and air closing structure used on the atomizer. Background Art

[0002] The inhalation vapor mist generating device currently used is generally a device that uses electric heating to atomize a special liquid, and the most commonly used product is the so-called "electronic cigarette". The product includes an atomizer, and an electrically heated atomizing component is arranged inside the atomizer, which is called an atomizing core.

[0003] The electronic cigarette atomizer core is generally fixed on a base inside the atomizer, with the upper end connected to the inhalation airway and the lower end connected to the air inlet and the dual electrodes. The cavity between the outer side of the atomizer core and the atomizer shell is an oil storage tank for storing smoke oil. The atomizer core itself is provided with an oil inlet hole, and the smoke oil in the oil storage tank can enter the inside of the atomizer core through the atomizer core oil inlet hole for heating and atomization. The atomizer core itself has three channels, one is the steam mist outlet, which is used to connect the inhalation airway; the other is the air inlet, which is connected to the air flow inlet; the steam mist outlet and the air inlet are respectively located at the upper and lower ends of the atomizer core and penetrate the atomizer core. The other is the oil inlet, which is an opening on the side wall of the atomizer core. Since it is necessary to ensure smooth airflow during smoking, the air inlet and the steam mist outlet need to be exposed to the air flow channel for a long time and connected to the outside atmosphere. At this time, the inside of the atomizer core is connected to the smoke oil inlet, and the smoke oil in the oil storage tank may enter the inside of the atomizer core through the oil inlet hole, and then leak out from the steam mist outlet or the air inlet. Due to the necessary ventilation structure of the atomizer core and the atomizer, oil leakage is basically inevitable.

[0004] In view of the existence of the above problems, various atomizer oil leakage prevention structures have emerged.

[0005] A typical example is to set up a rotating anti-leakage structure. It is a structure that rotates to close the oil inlet hole of the atomizer core. A cylindrical cover is set on the outside of the atomizer core. The cover has the same oil inlet hole as the atomizer core. By rotating the cover, the oil inlet hole of the atomizer core and the oil inlet hole of the cover can be aligned, staggered or between them. The function of closing and opening the oil inlet channel is realized to avoid oil leakage. However, the defects of this structure are: (1) The rotating cover needs to be connected to an external rotating device to achieve the purpose of controlling the rotation of the cover, which will cause a complex structure. The rotating cover is located in the oil storage tank, and the external control device must be located outside the atomizer, so a complex sealing device must be required to prevent oil leakage during rotation. (2) The outer shell of the atomizer core and the rotating cover are both metal cylindrical structures, and they must be guaranteed to rotate with each other, so a certain gap must be set to achieve this. However, it is difficult to set a sealing device between the inner and outer wall surfaces of the cylindrical metal, resulting in a poor sealing effect. The e-liquid is liquid and can penetrate any pore. As long as there is a small gap, oil leakage will still occur. The problem of oil leakage cannot be fundamentally solved. The oil leakage will still cause the e-cigarette to be contaminated by the e-liquid inhaled airway, affecting the inhalation feeling.

[0006] Later, a sliding oil-locking structure appeared, in which a sliding sleeve is set on the outside of the atomizer core. The sleeve covers the atomizer core, and the sliding sleeve itself does not have an oil inlet hole. When the sliding sleeve slides to cover the atomizer core oil inlet hole, the atomizer core oil inlet channel is blocked to prevent the atomizer core from entering and leaking oil. However, since some smoke oil will still remain inside the atomizer core after the atomizer core oil inlet hole is blocked, a small amount of smoke oil will still leak out, which still cannot completely solve the problem of the electronic cigarette's airway being contaminated by smoke oil.

[0007] In addition, the above-mentioned structures are generally considered from the perspective of closing the oil inlet hole of the atomizer core. In fact, the leakage outlet of the smoke oil is also a very important issue. For example, the air inlet and the vapor mist suction airway of the atomizer. Since the smoke oil will leak from here, many atomizers are equipped with an adjustment ring at the air inlet. The adjustment ring can control the opening and closing of the air inlet, which can not only realize the air intake adjustment function, but also achieve a certain anti-leakage effect. However, in the current electronic cigarette products, it is rare to set an anti-leakage device on the suction airway. The suction airway is in direct contact with the oral cavity as the smoke outlet, and it is even more necessary to prevent the smoke oil from entering the smoke outlet. At the same time, it is also necessary to set a device to close the suction airway to prevent dirt from falling into the inside of the atomizer core.

[0008] In short, there are indeed many atomizers with oil-blocking structures in the prior art electronic cigarettes, but there is no atomizer structure that can achieve both air-blocking and oil-blocking. Moreover, as long as the airway of the electronic cigarette is open, it cannot completely avoid being contaminated by the electronic cigarette oil, nor can it prevent dirt from falling from the mouthpiece into the atomizer core. When dirt enters the atomizer core, it will be heated or even ignited during heating and smoking, which will greatly affect the mouthfeel.

[0009] In view of the above reasons, the inventors have designed an atomizer structure with an oil locking device and an air shut-off device, so as to achieve the purpose of avoiding oil leakage and dirty suction of the air duct by simultaneously locking the oil and shutting off the air flow channel. Summary of the invention

[0010] The purpose of the present invention is to provide an atomizer oil-locking and air-closing structure, which has the dual functions of oil-locking and air-closing, and effectively prevents the problems of oil leakage and dirty smoke outlet.

[0011] The oil-locking and air-closing structure of the atomizer of the present invention comprises an atomizer core, an atomizer base and an exhaust air duct, wherein the atomizer core is arranged on the atomizer base. The exhaust air duct is sleeved on the outside of the atomizer core and can slide axially, and the exhaust air duct is provided with an oil-locking device and an air-closing device. The oil-locking device is an oil-blocking ring arranged at the bottom end of the exhaust air duct, and the air-closing device is a conical valve arranged in the exhaust air duct. The exhaust air duct can be slidably positioned between a first position and a second position. When the exhaust air duct is in the first position, the conical valve is separated from the vapor outlet of the atomizer core, and the oil-blocking ring is separated from the base. When the exhaust air duct is in the second position, the conical valve is pressed against the vapor outlet of the atomizer core, and the oil-blocking ring is pressed against the base.

[0012] In the above-mentioned atomizer oil locking and air shutoff structure, the conical valve is arranged in the inhalation air duct, and the arrangement position is located on the upper side of the atomization core vapor mist outlet. The central part of the conical valve is a downward solid cone, and the outer edge of the conical valve is provided with an air hole.

[0013] In the above-mentioned atomizer oil locking and air closing structure, a sealing gasket is provided at the vapor outlet of the atomizer core, and the sealing gasket is provided with a contact surface with an angle corresponding to the solid cone of the conical valve; when the inhalation airway is in the second position, the solid cone presses against the contact surface of the sealing gasket for sealing.

[0014] In the above-mentioned atomizer oil locking and air shutoff structure, the oil-blocking ring of the oil-locking device is arranged at the bottom of the suction air duct and is an annular body protruding outward, and a sealing gasket is arranged on the base of the atomizer; when the suction air duct is in the second position, the oil-blocking ring and the sealing gasket on the base are tightly sealed.

[0015] In the above-mentioned atomizer oil-locking and air-closing structure, the oil-blocking ring and the suction air duct are an integrally formed structure or a fixedly connected structure, and the conical valve and the suction air duct are a fixedly connected structure or an elastically movable connected structure.

[0016] In the above-mentioned atomizer oil-locking and air-closing structure, the atomizer is also provided with a top cover, and a sliding seal is provided between the suction and outlet air passage and the atomizer top cover.

[0017] In the above-mentioned atomizer oil-locking and air-closing structure, a locking device is arranged between the atomizer top cover and the suction air duct, and the locking device includes an annular locking groove arranged on the atomizer top cover and a locking block arranged on the outer wall of the suction air duct, and the locking block and the annular locking groove can be locked and positioned; there are two annular locking grooves.

[0018] In the above-mentioned atomizer oil-locking and air-closing structure, a locking device is arranged between the atomizer top cover and the suction air duct, and the locking device includes a locking block arranged on the atomizer top cover and an annular locking groove arranged on the outer wall of the suction air duct, and the locking block and the annular locking groove can be locked and positioned; there are two annular locking grooves.

[0019] In the above-mentioned atomizer oil-locking and air-closing structure, an axial conversion groove is provided between the annular grooves, and the axial conversion groove is communicated with the two annular grooves.

[0020] In the above-mentioned atomizer oil-locking and air-closing structure, the air inlet passage is provided with an elastic restoring device, and the elastic restoring device is a return spring arranged between the atomizer top cover and the air inlet passage.

[0021] Since the structure of the present invention is provided with a sliding suction airway sleeved on the outside of the atomizer core, when the suction airway is in the first position, the conical valve is separated from the atomizer core vapor outlet, so that the electronic cigarette vapor produced by the atomizer core can be sucked out from the atomizer core to the air vents on the outer edge of the conical valve, thereby achieving the purpose of smoking. At this time, the oil blocking ring is also separated from the atomizer core base, exposing the atomizer core oil inlet hole to the oil storage bin, so that the atomizer core can be adequately supplied with tobacco oil to ensure normal smoking. When smoking is not needed, the suction airway is slid down to the second position, at which time the conical valve contacts and presses against the sealing gasket of the atomizer core vapor outlet, cuts off the suction airway, shuts off the suction airway, avoids the pollution caused by oil leakage in the suction airway, and can also prevent external dirt from falling from the suction airway into the atomizer core. At the same time, at this time, the oil blocking ring contacts and presses against the sealing gasket on the base, blocks the atomizer core oil inlet hole, blocks the passage for tobacco oil to enter the atomizer core, and can reduce the occurrence of oil leakage in the atomizer core.

DETAILED DESCRIPTION

[0028] The present invention is described in detail below with reference to specific preferred embodiments in conjunction with the accompanying drawings, but the specific embodiments are limited to the explanation of the technical solutions of the present invention, and any description made therein shall not affect the limitation of the protection scope.

[0029] The overall design idea of ​​the present invention is to set a sliding suction airway on the outside of the atomizer core of the atomizer, set an oil blocking ring at the bottom of the suction airway, and set a conical valve inside the suction airway. The oil blocking ring is used to block the oil inlet channel of the atomizer core to achieve the oil locking function, and the conical valve is used to block the channel between the atomizer core vapor outlet and the suction airway to achieve the air shut-off function. And the oil locking and air shut-off functions can be realized simultaneously.

[0030] Embodiment 1: This embodiment is one of the preferred embodiments of the present invention.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the oil-locking and air-closing structure of the atomizer of this embodiment is arranged as follows: the electronic cigarette atomizer core 3 is mounted on the atomizer base 4 and is coaxially arranged at the central part of the atomizer base 4. An air inhalation passage 1 that can slide up and down axially is arranged on the periphery of the atomizer core 3. The air inhalation passage 1 is sleeved on the outside of the atomizer core 3, and the sliding direction is along the axial direction of the atomizer core 3.

[0032] like Figure 1 , Figure 2As shown, the inner wall of the inhalation airway 1 is sealed and slidably connected to the atomizer core 3 through a sealing pad 31 arranged at the vapor outlet of the atomizer core 3. A conical valve 2 is arranged inside the upper position of the inhalation airway 1, and the conical valve 2 is composed of a solid conical body 22 located in the central part and an air vent 21 arranged at the edge of the solid conical body. Therefore, the central position of the conical valve 2 is airtight, while the air vent 21 at the outer edge is airtight. The conical surface 23 of the conical valve 2 is arranged facing the sealing pad 31 of the atomizer core, and the angle of the contact surface 311 at the upper end of the sealing pad 31 corresponds to each other. In other words, when the conical valve 2 is pressed against the sealing pad 31 of the atomizer core, the conical surface 23 of the conical valve and the contact surface 311 of the sealing pad 31 just correspond to each other to achieve sealing, thereby shutting off the air flow channel between the atomizer core 3 and the inhalation airway 1. Moreover, since the contact surface angles correspond to each other, the contact area will increase, the sealing area will also increase, and the effect will also increase.

[0033] like Figure 1 , Figure 2 As shown, at the bottom position of the exhaust air duct 1, there is an outwardly protruding oil-blocking ring 11, which is arranged at the bottom end of the exhaust air duct 1 and is at the lowest end of the exhaust air duct 1. The oil-blocking ring 11 is an annular platform that protrudes outward along the exhaust air duct 1. In order to cooperate with the structure of the oil-blocking ring 11 to realize the sealing and oil-locking function, a sealing gasket 41 is arranged on the upper side of the atomizer base 4, and a hole is opened at the central position of the sealing gasket 41, and a smoke oil channel 411 is formed together with the atomizer core 3 at the central position. The height position of the oil inlet hole 32 of the atomizer core 3 is just located at the position of the smoke oil channel 411, so as to ensure that the smoke oil enters the atomizer core oil inlet hole 32 through the smoke oil channel 411 for atomization.

[0034] like Figure 1 , Figure 2 As shown, the outer diameter of the oil passage 411 is smaller than the outer diameter of the oil blocking ring 11, that is, the inner diameter of the sealing gasket 41 is smaller than the outer diameter of the oil blocking ring 11. When the oil blocking ring 11 contacts the sealing gasket 41, the oil blocking ring 11 can block the oil passage 411, thereby blocking the oil from entering the oil passage of the atomizer core oil inlet hole 32, and the oil cannot enter the atomizer core 3.

[0035] The conical valve 2 of this embodiment is fixed in the suction airway 1 by interference fit, and the oil-blocking ring 11 is integrally arranged at the bottom of the suction airway 1. Therefore, the axial positions between the conical valve 2 and the oil-blocking ring 11 are fixed, and the axial distance between them is also fixed. When making, it is necessary to accurately calculate the axial distance between the two in advance, so as to facilitate the linkage of the conical valve 2 and the oil-blocking ring 11, and to block the smoke oil channel 411 and the suction airway 1 at the same time during the linkage process. That is, when the oil-blocking ring 11 is pressed against the base sealing gasket 41, the inclined surface 23 of the conical valve 2 can be pressed against the contact surface 311 of the sealing ring 31, and the functions of locking oil and shutting off air are realized at the same time. When selecting the sealing gasket material, soft materials with a certain elasticity should be selected as much as possible, such as silicone. The purpose of setting soft sealing gaskets 41 and 31 is that when there is a slight assembly error, the compressibility of the soft material can make up for the assembly error, and also achieve a good sealing effect.

[0036] like Figure 1 As shown, it is a cross-sectional structural diagram of the inhalation airway 1 in the first position in this embodiment. At this time, the electronic cigarette is in a smoking state, and the inhalation airway 1 is lifted to a position close to the upper end of the atomizer, and the oil blocking ring 11 is also lifted to a position close to the atomizer core 3. At this time, the oil blocking ring 11 is separated from the sealing gasket 41 of the base, thereby opening the oil inlet channel 411, and the smoke oil can enter the inside of the atomizer core 3. At the same time, the conical valve 2 located on the inner side of the inhalation airway 1 is also lifted, and the conical valve 2 is separated from the sealing gasket 31 of the vapor outlet of the atomizer core, and the vapor outlet at the upper end of the atomizer core is opened. The atomized smoke will pass through the vapor outlet and go around the air hole 21 on the outer edge of the conical valve and rise, and can be sucked out through the inhalation airway 1 to achieve the function of smoking.

[0037] like Figure 2 As shown, it is the cross-sectional structure of the inhalation air duct 1 in the second position in this embodiment. In this position, the electronic cigarette is in the state of locking oil and closing air, that is, the idle state. At this time, the inhalation air duct 1 is pressed down, and as the inhalation air duct 1 is pressed down, the oil blocking ring 11 presses against the base sealing gasket 41, blocks the oil inlet channel 411, and cuts off the oil inlet channel, which can avoid or reduce oil leakage. At the same time, the conical valve 2 is also pressed down, pressing against the sealing gasket 31 set at the vapor outlet of the atomizer core, and cutting off the inhalation air duct 1. Thereby preventing the smoke oil leaked from the atomizer core 3 from flowing out of the inhalation air duct 1, and at the same time, it can also block the external dirt from entering the channel inside the atomizer core 3.

[0038] like Figure 4As shown, as for the problem of how to achieve axial sliding of the inhalation air duct 1 around the atomizer core 3 in this embodiment, it can be achieved through the following structure: at the inner upper end of the inhalation air duct 1, it can be fixedly connected to an electronic cigarette smoking nozzle 5, and the axial sliding of the inhalation air duct 1 can be achieved by axially moving the electronic cigarette smoking nozzle 5. And a sliding sealing structure is provided between the upper outer edge of the inhalation air duct 1 and the atomizer top cover 6. Specifically, a sealing ring 62 can be provided on the top cover to seal the smoke oil in the atomizer to ensure that the smoke oil does not leak when the inhalation air duct 1 slides axially. In order to achieve axial positioning of the axially sliding inhalation air duct 1, a two-stage locking structure can be provided between the atomizer top cover 6 and the outer wall of the inhalation air duct 1, so that the inhalation air duct 1 can be locked and positioned in the first position or the second position. As shown Figure 4 In the structure shown, a block 13 is arranged on the outer wall of the suction airway 1, an upper annular groove 63 and a lower annular groove 64 are arranged at the rotation connection between the atomizer top cover 6 and the suction airway, and a conversion groove 61 is arranged on one side symmetrical to the connection, and the conversion groove 61 is communicated with the upper and lower annular grooves respectively, so that the block 13 can realize the position conversion between the upper and lower annular grooves through the conversion groove 61. When the suction airway 1 is located at the first position, the block 13 and the upper annular groove 63 are locked for axial positioning, and when the suction airway 1 is located at the second position, the block 13 and the lower annular groove 64 are locked for axial positioning. The conversion between the first position and the second position is realized by rotating the smoking nozzle 5 and then replacing the annular groove through the conversion groove 61. Of course, the above-mentioned annular groove and block can be interchanged, for example, the annular groove is arranged on the outer wall of the suction airway, and the block is arranged on the atomizer top cover. However, since it is necessary to be positioned at the first position and the second position respectively, there should be two annular grooves for positioning.

[0039] Example 2: This example is an improved implementation based on Example 1. In Example 1, the conical valve 2 is a fixed structure, so the axial distance between it and the oil blocking ring 11 is fixed. Only by pre-designing the fixed position and accurately installing and positioning it can the conical valve 2 and the oil blocking ring 11 be linked to lock the oil and shut off the air at the same time. A small assembly error can be achieved by plastic deformation of the soft sealing gasket, so the effect is slightly worse. The improvement of this example is to elastically set the conical valve 2 on the inner side of the suction and outlet airway 1, so that the conical valve 2 can slide elastically within a certain axial distance, and then elastically block the atomization core vapor outlet.

[0040] For the specific structure, see Figure 4As shown, the edge of the conical valve 2 is clamped between the clamping platform and the clamping ring 25 on the inner side of the inhalation air passage 1, so that the conical valve 2 has a certain axial activity space in the inhalation air passage 1, and a pressure spring 24 is arranged between the conical valve 2 and the clamping platform on the inner wall of the inhalation air passage 1. The elastic pressure of the pressure spring 24 and the activity space of the conical valve 2 are relied on to realize the elastic tightness of the atomizer core sealing gasket 31, thereby avoiding the problem of poor sealing caused by the assembly error of the fixed structure.

[0041] In this embodiment, an elastic recovery device, such as a return spring 12, may be provided between the outer wall of the inhalation airway 1 and the atomizer top cover 6 to help achieve elastic sliding and elastic positioning of the inhalation airway 1 and maintain positioning stability.

[0042] The above description is based on the preferred embodiment. On the basis of the above embodiment, those skilled in the art can also make equivalent structural replacement changes. For example, replacing the conical valve 2 with an arc valve, a trapezoidal valve, etc. can achieve the basic purpose of the present invention and achieve the effect of shutting off the air. Removing the outward protruding structure of the oil blocking ring and directly extending the cylinder of the suction airway 1 so that it directly blocks the oil inlet hole of the atomizer core in the second position can also achieve the function of locking the oil.

[0043] In summary, the present invention has described its specific implementation methods with various specific embodiments. For those skilled in the art, it is still possible to obtain structural changes similar to the present invention based on the basic ideas of the present invention. Any design and changes that do not deviate from the basic ideas of the present invention should fall within the protection scope of the present invention.
